Title: Improvements in or relating to Glass Fibre Reinforced Tubes.
IPC: B29C53/80
Filed: 1968-06-04
Abstract: 1,182,893. Making pipes. KLOCKNERWERKE A.G. 4 June, 1968 [10 June, 1967], No. 26595/68. Heading F2P. In a process for making glass fibre-reinforced tube wherein glass fibre yarns 5, which have an electrically conductive surface, are first applied axially of a mandrel and then glass fibre yarns are helically wound about the axiallyextending yarns, a mixture of synthetic plastics or resinous material and hardener is applied by an electrostatic spray unit 9 to the axiallyextending yarns prior to applying the helicallywound yarns. The yarns 5 are drawn from spools 6, pass through braking and tensioning rollers 7, and distributed around the periphery of an axially-moving mandrel 1 by a guide and distributer ring 8. Downstream of the distributer ring and upstream of a rotating winding machine applying the helically wound yarns, the axially-extending yarns pass through the spray unit 9 comprising four spray bells 11 arranged circumferentially of the mandrel. Two pumps 12 feed synthetic plastics or resinous material and a hardener through separate conduits 13, 24 to each bell which produces a finely atomized and electrically charged mixture. The mandrel, which may be of plastics material, is axially moved by a chain-driven carriage 2, 3. After passage through the winding machine, the tube is cured in an oven. The axially-extending glass fibre yarns may be metallized to provide an electrically conductive surface.

Title: Improvements in or relating to negative-impedance repeaters for loaded cabies
IPC: H04B3/16
Filed: 1955-09-19
Abstract: 772,994. Modifying line circuits to improve transmission. MOULON, J. M. Sept. 19, 1955 [Nov. 29, 1954; Dec. 31, 1954], No. 26757/55. Class 40 (4). In a loaded line 41 including a negative impedance repeater comprising a converter 1 and a passive network composed of two resistors 5, 6, the latter of which is shunted by a condenser 7, the repeater is coupled to the lines by the windings of a transformer 3 and condensers 14, 15 are connected in shunt with the line on either side of the winding to present to the repeater an impedance which resembles that of an unloaded line whereby the simple passive network causes a substantially level gain over the whole of the working frequency range of the line. The condensers which are of the order of tens of thousands of micro, microfarads, have a capacity given by C=1/Rc.#max, where Rc is the real characteristic impedance in ohms of the loaded line measured at the midpoint of a section and #max is the angular frequency corresponding to the upper limit of the frequency band to be transmitted. The repeaters are normally disposed at a mid-point between two loading coils, but may be placed at any point providing the condenser capacity together with the line capacity on both sides equals the calculated value plus the halfsection line capacity. The advantage of the arrangement is discussed with reference to impedance curves, Fig. 4 (not shown).

Title: An improved machine for corrugating tubular metal bodies
IPC: B21D15/06
Filed: 1926-10-27
Abstract: 275,826. Rhodes, C. J. Oct. 27, 1926. Corrugating. - In a machine for corrugating tubular metal bodies such as drums of the type comprising upper and lower rollers each formed of a number of axially movable members normally spaced apart by springs for compensating for the decrease in length of the body during corrugating, the upper roller is adjustable vertically to vary the initial distance between the rollers and horizontally to secure parallelism or otherwise between the axes of the rollers. The lower roller consists of two parts 5, 6 which are keyed to a driven spindle 4 supported in bearings 3, 8<a>, 8, the parts being normally pressed outwards by spring plungers 84. The part 8<a> may have arcuate plates so as to centre, the work. The upper rollers 55, 56, which are of larger diameter than the lower rollers to increase the area of contact, are freely mounted on roller bearings on a spindle 54 and have spring plungers 88 engaging a freely mounted distance piece 87, which provides a fly wheel effect. The lower roller is driven by spur gear 9, 37 from a spur wheel 15 which may be clutched to a shaft 13 driven by chain gear from a motor. The clutch has two sections 16 engaging a recess in the wheel and provided with screwed sleeves in which are mounted right and left handed screwed rods connected by a boss keyed to the shaft 13. The clutch is put in by a hand lever 31 through levers and rods connected to a lever 28 engaging pins in a block 26 mounted on a sleeve 25, which is connected by links 24 to the squared central portions 23 of the threaded rods. The upper roll spindle is mounted in bearings in a member 49 which is connected by screws 58 and slots to a. slide 59 on which it may be angularly adjusted by bolts 48<b>. The upper part of the slide 59 is U-shaped to receive a body 60 carrying a roller 64. The body is secured by screws to the slide 59 and is adjustable thereon to vary the vertical position of the roller 55, 56 by a screw-adjusted wedge 80. The member 49 is slotted to receive a rod 48 which, through rods 47 and a counter-weight 57 presses the roller 64 into contact with a cam 65 which feeds down the roller 55, 56 during corrugating. The cam is mounted on a shaft 66, driven by gearing 72, 70. 69 from the shaft 13, the shaft 66 being disconnectible from its driving gear by a hand-operated clutch 74. The cam may be prevented from racing by a pivoted brake held in contact therewith by a weighted lever. The tubular body is pushed over the lower roller against a stop 105 and a U-shaped plate 90 pivoted at 92 and operable by a hand lever through links 95, 96 is then lowered to engage the other end of the body. The links 95, 96 are provided with lugs to abut against each other when the hand lever flexes them beyond their common centre so as to maintain the plate 90 vertical. After corrugating is completed and the upper roller has returned to its raised position, the body is lifted free of the lower roller by strips 106 secured to pivoted members 107 operated by a pedal and the body is removed.

Title: A method of treating molten iron-bearing slag for the recovery of the iron
IPC: C21B13/12
Filed: 1959-08-06
Abstract: A process for the recovery of iron from molten iron-bearing slag comprises mixing the slag with iron ore, flux, and solid reducing agent to produce a semi-molten mass, reacting the mass to reduce the iron ore to metallic iron, heating the mass to such temperature that the iron becomes molten, and separating the iron from the semi-molten residue.  The reducing agent may be coke breeze, and the semi-molten mass may be reacted in an electric furnace at 1200 DEG  C. for two hours before heating to 1300 DEG  C. at which temperature the molten iron may be separated from the semi-molten residue.
Patent GB-673641-A (GB)
Title: Improvements in or relating to the production of edible nut meats, such as peanut butter
IPC: A23L25/00
Filed: 1948-10-15
Abstract: A stable nut meat which also possesses marked resistance to deterioration is prepared by incorporating therein a monoalkyl or monoalkylene ester of citric acid, e.g. .002-1 per cent, or a dialkyl or dialkylene ester of citric acid, e.g. .5-5 per cent, the alkyl and alkylene groups in the diester having at least 8 carbon atoms and any number in the monoester though advantageously they contain the same number of carbon atoms as the dialkyl or dialkylene ester.  The esters may be incorporated in the whole nut meat or in a part thereof by roasting the nut meat in an oil containing the esters, or incorporated in a finely divided mixture of the particles derived from the whole or degerminated nut meat.  The mono and diesters may be produced simultaneously by reacting the required amount of anhydrous citric acid or citric acid monohydrate with an alkyl or alkylene alcohol or mixtures thereof.  To facilitate uniform dispersion of the esters in the oil a solubilizing agent may be employed in which the ester is dissolved and the resulting solution mixed into the oil and nut meat.  Examples of the solubilizing agents are the monoglycerides of fatty acids having at least 10 carbon atoms, unsubstituted aliphatic monohydric alcohols having at least 6 carbon atoms, fatty acids having at least 10 carbon atoms, dialkyl or dialkylene esters of citric acid in which the alkyl or alkylene group has at least 8 carbon atoms and trialkyl or trialkylene esters of citric acid, e.g. trialkyl or alkylene citrates in which the alkyl or alkylene group has at least 8 carbon atoms.  In an example a mixture of 15-20 per cent monostearyl citrate, 50 per cent distearyl citrate and 35-30 per cent tristearyl citrate is added to peanut oil so that the peanut butter to which the oil is added will contain about 2 per cent by weight of the mixture of citrates.  Specification 625,683 is referred to.

Title: Improvements in the remote control of multiphase electric motors
IPC: H02P1/08
Filed: 1950-11-04
Abstract: 681,776. Control of motors. BROOKE, W., and BALDWIN, H. T. Nov. 4, 1950, No. 26985/50. Class 38 (iii) Relates to a system comprising a remote control switch D having "off", "start", and "run" positions, means being provided to prevent an overload control from being rendered ineffective when the control switch is held in the starting-position. When the supply is switched on to lines L<SP>1</SP>, L<SP>2</SP>, L<SP>3</SP>, and the control switch is in the "off" position D', relay B is energised through a common trip bar H of overload relays E, F, G, and through contact A<SP>3</SP>. The closure of contact B<SP>3</SP> maintains the relay B energised independently of the contact A<SP>3</SP>. Upon movement of the switch D to starting-position D<SP>2</SP>, a relay A is energised from a transformer T through rectifier K, a main contactor C then being closed through contacts A<SP>2</SP>, B<SP>2</SP>. The switch D is then allowed to move to the running position D<SP>3</SP> whereupon a resistor L is connected in series with coil A<SP>1</SP> so allowing the relay A normally to remain closed, but not permitting reclosure if the power supply is re-instituted after failure and the switch D remains in its running- position. If the motor is over-loaded and at the same time the control switch is held in the position D<SP>2</SP>, the trip bar H opens to de-energise relay B. Opening of contacts B<SP>2</SP> de-energises contactor C to stop the motor although relay A remains energised. Reclosure of the overload control does not re-energise relay B since contacts A<SP>3</SP>, B<SP>3</SP>, are open, it being necessary to return the control switch to the position D<SP>1</SP> in order to re-start the motor.

Abstract: 999, 763. Xerographic fusing apparatus. RANK-XEROX Ltd. July 26, 1961 [Aug. 1, 1960], No. 27139/63. Heading G2H. [Also in Division H5] Apparatus for fixing a xerographic powder image on a web comprises drive means to effect movement of the web along a path, on electrical heater carried on a support member and mounted adjacent to the path such that the member can be moved into and away from an operative position by resilient means, means for both energizing the heater and moving the member into the operative position concomitantly with initiation of movement of the web and means responsive on stoppage of the web to allow the resilient means to move the support member away from the operative position. As shown in the inoperative position (Fig. 2) the support member consists of two plates 60 and 61 which contain eight heating elements 50. These plates are hinged on shaft 75 and held in the inoperative position by coil springs 86 and 87 attached to shaft 76. To move the plates into the operative position, a switch operates motor 91 which through driving mechanism 92-95 causes cam 96 to rotate and forces the follower arms 79 and 80 to move so that plates 60 and 61 are pivoted about shaft 75 to the horizontal operative position. This switch also energizes the armature of solenoid SO L-1 to which pin 101 is attached which rotates levers 102 and 103 and their connected latches 104, 105 about their pivots 109,110 to secure arms 69 in the operative position. The assemblies 104 and 105 have a front plate 111 which may be bent back to the backing plate 112 to retain shaft 76. To return the plates to the inoperative position, the solenoid is de-energized (e.g. by stoppage of the web or by pressing a stop switch) causing springs 115 and 116, secured between frame and levers 102 and 103, to move these levers so that the latch assemblies are pivoted outwards to release shafts 76 back to the inoperative position. A complete xerographic apparatus incorporating the above fuser is described.
